Its not a controller, its an OptimizIR

The days of using a “controller” are over, imagine having the ability to select an antenna that is optimized for maximum gain, maximum front-to-rear or a combination of the two… at a click of a button!
Create your own custom antenna models using 3rd party software such as AutoEZ, then download to your OptimizIR via mini SD card.

  • Selected antenna pattern (normal, bi-directional and 180)
  • Forward gain in dBi
  • Front-to-rear in db
  • Combination of gain / front-to-rear
  • Antenna beam-width
  • Bar graph for visual confirmation of gain / FR


180 Degree mode: The 180 mode allows users to electrically “rotate” the antenna 180 degrees opposite the forward direction beam heading. This is accomplished with the simple press of a button, and in seconds, the transformation is complete – the Yagi is pointing in the exact opposite direction.

Bi-Directional Mode: The Bi-Directional mode function operates in a similar manner to the 180 degree mode, except when enabled, the antenna operates as a hybrid Yagi, with forward gain occurring in opposite directions, simultaneously. For the SteppIR BigIR and SmallIR verticlas, when this mode is enabled the antenna changes from 1⁄4 wave to 3⁄4 wave.

Element Retract Mode: With the Element Retract Mode, the user can retract all the elements
on a SteppIR antenna to the home position, and the controller will then power down automatically. Retracting elements is an extremely valuable option in the event of inclement weather such as high winds, snow or radial icing. During lightning events, a retracted antenna greatly reduces the conductive area of the antenna platform.

Transceiver Interface: Automatically adjusts each element of the antenna as the radio tunes.

Tuning Relay: Lock-out relay connects via PTT cable to RF power source and prevents the amplifier from transmitting while the SteppIR antenna is being tuned.

Advanced Lightning Protection: Each driver chip inside the OptimizIR has a relay in front of it that protects against lightning, nearby lightning incidents and dead shorts. Module will only work if the antenna is not in the process of adjusting when the vent occurs.
